牧草及其种子生产,受许多因素的制约,其中气侯、太阳光能等,生产者很难使之改变,但人可通过改善管理,增加土壤有效成分的含量等措施,最大限度地发挥其生产潜力,获得较高的牧草及种子产量。本文的目的是对努伊多年生黑麦草(Lolium perennial L.)进行不同的封闭,探索最佳封闭期,以获得最好的牧草和种子产量。
Herbage and its seed production are constrained by many factors, of which climate and solar energy can hardly be changed by producers. However, people can maximize their benefits by improving management and increasing the amount of soil active ingredients Potential for production, access to higher pasture and seed production. The purpose of this paper is to perform different closures on Lolium perennial L. and to explore the optimal closure period for the best forage and seed yield.
